So after going all the way to escalated support, the gentleman on the phone told me a couple things to try that finally fixed my issue with this.
obviously I tried all the basics but didn’t work, what actually did work was resetting my phone network settings and going through my location services and turning things off for everything/apps that I don’t use or need locations for. I believe the problematic app was most likely the Alexa app in the end.
for context: every time I left home about 1 minute into the drive my CarPlay cut over to my cars phone audio speaker when you are on a phone call and it only comes from the console speaker, then when I came home the same thing would happen when I was about 100ft from my house. Driving an Acura Tlx 2022 with updated software. This followed me from my 12 pro max when upgrading to the 14 pro max. I always had to push my CarPlay button and just said “no” for it to connect back to my regular speakers.
